Nikon D800 User Manual (en)

e: Programmed Auto
In this mode, the camera automatically adjusts shutter speed and 
aperture according to a built-in program to ensure optimal 
exposure in most situations. This mode is recommended for 
snapshots and other situations in which you want to leave the 
camera in charge of shutter speed and aperture.
Flexible Program
In exposure mode e, different combinations of 
shutter speed and aperture can be selected by 
rotating the main command dial while the 
exposure meters are on (“flexible program”). 
Rotate the dial to the right for large apertures 
(small f-numbers) that blur background details 
or fast shutter speeds that “freeze” motion. 
Rotate the dial to the left for small apertures 
(large f-numbers) that increase depth of field or 
slow shutter speeds that blur motion. All 
combinations produce the same exposure. 
While flexible program is in effect, an asterisk 
(“U”) appears in the control panel. To restore 
default shutter speed and aperture settings, rotate the dial until the 
asterisk is no longer displayed, choose another mode, or turn the 
camera off.
